Investigation 9: Evolution Timeline
Students produce a scale model of the major events in the earth’s history. Students see a representation of the enormous amount of time over which evolutionary change has occurred. Through the scale model students are exposed to the relative ages of several important animal groups such as fish, dinosaurs, birds and primates. Through the scale model, they see that change is the hallmark of earth’s history and that groups are born, exist and often become extinct.

Investigation 11: Classification and Evolution
Classification provides an organized approach for understanding the unity and diversity of life.

In the most widely used classification system, taxonomists consider how organisms are related and group them on the basis of what is known about their evolutionary ancestry.

Structural homologies form the basis for classification. This approach produces a huge family tree that unites every living thing on Earth.

Taxonomic classification is not fixed. It depends on the interpretation of evidence and is open to change in response to new data.
